Problem 2.5

Norfolk to Williamsburg



What was Theo’s fastest recorded speed and when did it occur?

Theo’s fastest recorded speed was 20miles and I occurred from 70-90.

a. What was Theo’s slowest recorded speed and when did it occur?

Theo’s slowest speed was 15miles and it occurred from 30-50.

b. Describe the changes in Theo’s speed during the race?

At the beginning from minutes 10-70 he had a 10 minute interval but then after 80 minutes he speeded up.

c. The graph only shows Theo’s speed at 10-minute intervals; it does not tell us what happened between 10-minute marks. The paths below show five possibilities of how Theo’s speed may have changed during the first 10 minutes. Explain in writing what each connecting path would tell about Theo’s speed.

Theo’s 10-minute intervals look like No. 2 because it looks like he took up the speed but then he slowed down.

Follow Up
1. No, it wont be possible to represent Theo’s graph because nothing can pass without time passing.
2. Theo’s speed changed from 70 minutes to 90 minutes.
